2022-02-21meson: refine check for whether to look for virglrendererPaolo Bonzini
The check should be performed even if !have_system, as long as there is some hope that vhost-user-gpu will be built. Store into have_vhost_user_gpu whether vhost-user-gpu will be built; we will also use the variable to decide whether to look for libepoxy. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2021-11-04plugins/cache: implement unified L2 cache emulationMahmoud Mandour
This adds an implementation of a simple L2 configuration, in which a unified L2 cache (stores both blocks of instructions and data) is maintained for each core separately, with no inter-core interaction taken in account. The L2 cache is used as a backup for L1 and is only accessed if the wanted block does not exist in L1. In terms of multi-threaded user-space emulation, the same approximation of L1 is done, a static number of caches is maintained, and each and every memory access initiated by a thread will have to go through one of the available caches. An atomic increment is used to maintain the number of L2 misses per instruction. The default cache parameters of L2 caches is: 2MB cache size 16-way associativity 64-byte blocks Signed-off-by: Mahmoud Mandour <ma.mandourr@gmail.com> Signed-off-by: Alex Bennée <alex.bennee@linaro.org> Message-Id: <20210810134844.166490-3-ma.mandourr@gmail.com> Message-Id: <20211026102234.3961636-15-alex.bennee@linaro.org>

2021-09-06configure / meson: Move the GBM handling to meson.buildThomas Huth
The GBM library detection does not need to be in the configure script, since it does not have any user-facing options (there are no --enable-gbm or --disable-gbm switches). Let's move it to meson.build instead, so we don't have to clutter config-host.mak with the related switches. Additionally, only check for GBM if it is really required, i.e. if we either compile with OpenGL or with virglrenderer support.

2021-09-02plugins/cache: supported multicore cache modellingMahmoud Mandour
Multicore L1 cache modelling is introduced and is supported for both full system emulation and linux-user. For full-system emulation, L1 icache and dcache are maintained for each available core, since this information is exposed to the plugin through `qemu_plugin_n_vcpus()`. For linux-user, a static number of cores is assumed (default 1 core, and can be provided as a plugin argument `cores=N`). Every memory access goes through one of these caches, this approach is taken as it's somewhat akin to what happens on real setup, where a program that dispatches more threads than the available cores, they'll thrash each other Signed-off-by: Mahmoud Mandour <ma.mandourr@gmail.com> Message-Id: <20210803151301.123581-2-ma.mandourr@gmail.com> Signed-off-by: Alex Bennée <alex.bennee@linaro.org>
